IMPROVEMENT IN ARGAND GAS-BURNERS.

Specification forming part of Letters Patent No. 157,388, dated December 1, 1874; appication led May 14, 1874.

To all whom it may concern: i

Be it known that I, CHARLES D. GERVIN, of Williamsburg, in the city of Brooklyn, county ofKin gs and State of New York, have invented certain Improvements in Argand Gas-Burners, of which the following is a specification:

This invention consists in a gas-burner provided with an elastic bar to which is attached a two-way cock arranged between passages diametrically oppositeeach other, which communicate with the opening of the burner, whereby the communication from the supplypipe with the said passages may be cut oifby turning the cock, as will be hereinafter described.

In the accompanying drawing, Figure l is a central vertical section of a burner embodying my improvements, taken in the line w as of Fig. 3. Fig. 2 is also a central vertical section, taken in the line y y of Fig. 3. Fig. 3 is a transy verse horizontal section. Fig. 4 is a detail View of the elastic bar.

The burner B is made with its arms b b and annular chamber c in the ordinary form, the arms extending radially from the neck d, in the center of which is inserted a plug or two- Way cock, E, which may be either cylindrical or tapering, and which may be ground to its seat in the neck or nipple without the necessity for a seat made of a separate piece, as in the ordinary way. This plug E is formed with opposite each so that when in the position shown in two recesses, e e, diametrically Figs. l and 3 the communication is open between the neck d and the arms b and annular chamber c. The plug is formed with a rim or `lian ge on its lower end, and is inserted in the neck from below. Its upper end passes through a perforation in a bar, Gr, and a lever, H, and is upset or riveted down thereon. The bar G is made of elastic metal,` and lhas its ends formed to rest upon the arms b b near their junction with the circular portion of the burner. By this arrangement the plug E is attached and secured in place, and the elasticity ofthe bar keeps it in place in its seat. The lever H is attached to the plug by one end, and the other end is turned down and extends below the burner, to serve as a handle for operating the cock. At the ends of the arms b, where they communicate with the annular chamber c, are wire-gauze diaphragms J, which serve to break the current of gas and prevent whistling when the gas is burning.

What I claim as new, and desire to secure by Letters Patent, is-

rlhe elastic bar or spring G, in combination with the plug E, having a shouldered lower end to iitbeneath a shoulder in the neck d, and with the arms bbsubstantially as and for the purpose shown and described.
